Abstract

PURPOSE: Recycle lines are equipped on the tank for a slurry consisting of terephthalic acid and ethylene glycol and the slurry is circulated to effect the esterification, thereby producing esterification products of high quality with high fluidity.
CONSTITUTION: Terephthalic acid is stored in hopper 1 and quantitatively supplied to kneader 3 by TA metering unit 2, meanwhile ethylene glycol is quantitatively supplied from the other line to kneader 3 where they are made into a uniform slurry. The resulting slurry is stored in tank 4 and kept uniformly by circulation through recycle line 6 using pump 5. Wheh necessary, metering pump 7 is made to operate and the slurry is sent from recycle line 6 through branched lines to esterification tank 8 where bis-β-hydroxyethyl terephthalate and its oligomers are produced.
